ANGRY Boris Johnson tonight warned Iran it would face “consequences” for killing a Brit at sea in a drone strike.
The country was believed to be behind the hit on oil tanker Mercer Street that left the security guard and a Romanian sailor dead.
Government sources said a “range of options” was being drawn up for retaliation after Thursday’s attack off Oman.
A senior defence source said the most likely would be in cyberspace, warning “nobody will see it here but they will be left in no doubt you cannot kill a Brit unchecked”.
A Foreign Office insider added: “A British national was killed and we have to make clear there are certain lines that can’t be crossed.”
A Special Forces team flew out to join the stricken tanker and take charge of the investigation tonight.
A source said they did not believe the unnamed Brit had been deliberately targeted.
Iran’s ambassador to the UK was summoned for a dressing down in London, but insiders said the regime’s response was “all smoke and mirrors”.
The PM said Iran should “face up to the consequences of what they have done” and called on them to “respect freedoms of navigation”.
Chair of the Commons Defence Select Committee Tobias Ellwood said the attack “demands a proportionate response”.
The Mercer Street is managed by London-based Zodiac Maritime, part of Israeli billionaire Eyal Ofer’s Zodiac Group.
